Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1

[0041] Please see Figures 1-15 The present invention is a protection system for a dam slope, including a positioning mechanism 1, a telescopic support mechanism 2, a dam protection mechanism 3, and a reinforcement component 5. The positioning mechanism 1 is used to be installed at the toe of the dam. The positioning mechanism 1 includes two positioning columns 101 arranged opposite to each other. The positioning columns 101 are vertically arranged on the ground at the toe of the dam.

[0042] Telescopic support mechanism 2 is installed on positioning column 101 from bottom to top, and the length of telescopic support mechanism 2 gradually increases from bottom to top; dam protection mechanism 3 corresponds one-to-one with telescopic support mechanism 2, and the end of telescopic support mechanism 2 close to the dam body is rotatably connected to the corresponding dam protection mechanism 3. Dam protection mechanism 3 is used to abut against the sloping dam body of the dam, and two adjacent dam protection mechanisms 3 are horizontally attached to form a flow channel 4; reinforcement component 5 is set on dam protection mechanism 3, which is used to tightly fix dam protection mechanism 3 to the sloping dam body of the dam; a plant protection zone is formed between two adjacent dam protection mechanisms 3, and the plant protection zone is used to plant grass to achieve soil stabilization effect; by attaching dam protection mechanism 3 to the dam slope to support the dam slope, and planting grass in the plant protection zone formed between two adjacent dam protection mechanisms 3, the soil erosion on the dam can be greatly reduced, thereby increasing the stability of the dam protection.

[0043] In this embodiment of the invention, the positioning mechanism 1 further includes two soil-inserting cones 102 arranged opposite to each other. The soil-inserting cones 102 are fixedly arranged at the bottom of the positioning column 101. The two soil-inserting cones 102 are connected by a reinforcing frame 103. The soil-inserting cones 102 are used to achieve stable installation of the entire positioning mechanism 1 on the ground. The periphery of the positioning column 101 is provided with limiting ports 104 corresponding to the telescopic support mechanism 2 from bottom to top. A first magnet 105 is provided inside the limiting port 104.

[0044] In this embodiment of the invention, the telescopic support mechanism 2 includes a horizontal support component 21 and a movable support component 22, with the movable support component 22 and the horizontal support component 21 sliding together horizontally.

[0045] The horizontal support assembly 21 includes a horizontal support column 210. One end of the horizontal support column 210 is fixedly fitted with a support ring 211 that is sleeved on the positioning column 101. The inner wall of the support ring 211 has two mounting cavities 212, and the outer wall of the support ring 211 has radial holes coaxial with the corresponding mounting cavities 212. A first elastic element 213 is disposed inside each mounting cavity 212. The end of the first elastic element 213 has a limiting member 214 that slides within the mounting cavity 212 and is adapted to a corresponding limiting port 104. An unlocking rod 215 slides within the radial hole and is threadedly engaged with the threaded opening on the corresponding limiting member 214. The support ring 211 on the horizontal support assembly 21 is sleeved on the positioning column 101. When the telescopic support mechanism 2 moves down the positioning post 101 to the corresponding limiting port 104, the first magnet 105 attracts and inserts the limiting member 214 into the limiting port 104, thereby fixing the position of the entire telescopic support mechanism 2 on the positioning post 101. When it is necessary to remove the telescopic support mechanism 2 from the positioning post 101, the unlocking rod 215 is pushed so that it fits into the threaded opening on the limiting member 214. The unlocking rod 215 is then rotated to make it threaded into the threaded opening on the limiting member 214. At this time, simply pull the unlocking rod 215 to disengage the limiting member 214 from the corresponding limiting port 104, and the entire telescopic support mechanism 2 can be separated from the positioning post 101.

[0046] In this embodiment of the invention, a sliding cavity 216 is provided at the other end of the horizontal support column 210. A second elastic element 217 is provided inside the sliding cavity 216. The sliding cavity 216 is connected to the limiting slide 218 at the top of the horizontal support column 210. Two ear plates are provided at the top of the horizontal support column 210 near the support ring 211. A hand shaft 219 is rotatably connected between the two ear plates. A rope winding wheel 2110 is fixedly provided on the hand shaft 219 between the two ear plates. By rotating the hand shaft 219, the rope winding wheel 2110 can be rotated. Then, through the linkage of the tension rope 225, the relative sliding between the movable support component 22 and the horizontal support component 21 can be realized, thereby realizing the adjustment of the length of the entire telescopic support mechanism 2.

[0047] In this embodiment of the invention, the movable support assembly 22 includes a movable support column 221. One end of the movable support column 221 is fixedly provided with a movable plate 222 that slides with the sliding cavity 216. The movable plate 222 is fixedly connected to the second elastic element 217. The other end of the movable support column 221 is provided with a rotating seat 223. The top of the movable plate 222 is provided with a rope tie 224 that slides with the limiting slide 218. The rope reel 2110 is connected to the rope tie 224 by a tension rope 225.

[0048] By rotating the hand shaft 219, the tension rope 225 drives the movable support component 22 to move horizontally, thereby adjusting the horizontal distance between the telescopic support mechanism 2 and the dam slope. Then, the dam protection mechanism 3 is rotated and set on the telescopic support mechanism 2, thus enabling support at different heights on the dam slope and simultaneously meeting the support and protection requirements for dam slopes with different gradients.

[0049] In this embodiment of the invention, the dam protection mechanism 3 includes a dam protection plate 301, and a horizontal water guide plate 302 is provided on the surface of the dam protection plate 301, forming a horizontal water guide cavity between the horizontal water guide plate 302 and the dam protection plate 301.

[0050] Both ends of the dam protection plate 301 are fixedly equipped with longitudinal water guide plates 303. Adjacent longitudinal water guide plates 303 are fitted together to form a flow channel 4. The flow channel 4 is connected to the horizontal water guide cavities on both sides through the inlet 304. Through the horizontal flow guiding effect of the horizontal water guide plates 302 set on the surface of the dam protection plate 301, and the flow channel 4 set between adjacent horizontal water guide plates 302 in the horizontal direction, rainwater on the dam slope can be diverted away, greatly reducing the water and soil loss caused by water erosion on the dam slope and increasing the protection effect on the dam slope.

[0051] In this embodiment of the invention, a connecting seat 305 is fixedly provided at the bottom of the dam protection plate 301. Two fixed plates 307 are slidably connected inside the limiting groove 306 provided on the surface of the connecting seat 305. The fixed plates 307 are connected by a third elastic element 308. A rotating shaft 309 is fixedly provided on the side wall of the fixed plate 307 relative to the third elastic element 308. The rotating shaft 309 is rotatably engaged with the corresponding rotating seat 223. Under the compressive elastic potential energy of the third elastic element 308, the two oppositely arranged rotating shafts 309 are rotatably engaged with the corresponding rotating seat 223, which facilitates the dam protection mechanism 3 to be detachably rotated and engaged with the movable support column 221.

[0052] In this embodiment of the invention, the surface of the dam protection plate 301 is provided with a plurality of fixing through holes 310, and threaded grooves 311 are provided on both the left and right sides of the fixing through holes 310.

[0053] The reinforcement component 5 includes a reinforcement column 501 that is clearance-fitted with the fixed through hole 310. One end of the reinforcement column 501 is fixedly provided with a connector 502, and the connector 502 is threadedly connected to the threaded groove 311 by a fastener 503. The reinforcement column 501 has an insertion channel 504 that passes through the connector 502, and the periphery of the reinforcement column 501 has a discharge port 505 that communicates with the insertion channel 504. The reinforcement component 5 is inserted into the corresponding concrete filling hole, and the connector 502 is fixed to the dam body protection plate 301 by the fastener 503. Concrete is transported into the reinforcement column 501 through the insertion channel 504 and enters the concrete filling hole along the discharge port 505, thereby realizing the fixation between the reinforcement component 5 and the dam body. Specific Implementation Example 2

[0055] A construction method for a dam slope protection system includes the following steps:

[0056] S1. Insert the soil-inserting cone 102 into the ground at the foot of the dam according to the design drawings, thereby realizing the installation of the entire positioning mechanism 1;

[0057] S2. The telescopic support mechanism 2 is sleeved on the positioning post 101 and slid down to the lowest limiting port 104. Under the magnetic attraction between the first magnet 105 and the second magnet on the limiting member 214, the limiting member 214 is attracted and inserted into the limiting port 104, thereby fixing the position of the telescopic support mechanism 2 on the positioning post 101. The installation of all telescopic support mechanisms 2 is achieved through this installation method.

[0058] S3. Press the two fixing plates 307 to align the rotating shaft 309 with the rotating hole on the rotating seat 223. After releasing the fixing plates 307, the rotating shaft 309 and the rotating seat 223 are connected under the action of the compressive elastic potential energy of the third elastic element 308. This realizes the rotational connection of the dam protection mechanism 3 at the end of the telescopic support mechanism 2. The installation of all dam protection mechanisms 3 is realized through this installation method.

[0059] S4. Adjust the length of the telescopic support mechanism 2 by rotating the hand shaft 219 until the dam protection plate 301 is attached to the dam's inclined dam body. At this time, the fixed through hole 310 corresponds to the concrete filling hole on the dam's inclined dam body, and the diameter of the concrete filling hole is larger than that of the fixed through hole 310.

[0060] S5. Insert the reinforcement component 5 into the corresponding concrete filling hole, and fix the connector 502 to the dam body protection plate 301 with the fastener 503. Concrete is transported to the inside of the reinforcement column 501 through the insertion channel 504 and enters the concrete filling hole along the discharge port 505, thereby realizing the fixation between the reinforcement component 5 and the dam body.
